1. Method for unloading a container having packages with a rail device comprising at least one rail, wherein a hand element displaceable in the longitudinal direction of the rail is provided on the at least one rail, wherein the hand element has a plurality of finger elements, wherein the finger elements each have at least two flexible flank elements extending jointly from one end of the finger element to the opposite end of the finger element, wherein in each case the at least two flexible flank elements of the finger elements are each connected flexibly to each other via a plurality of webs, so that the finger elements can each be adjusted from at least a curved position into at least an extended position and back, wherein the packages are stacked in the container, wherein the stacked packages form a front face,
in which the rail device is brought close to the front face of the stacked packages,
in which the at least one hand element grips at least one package from the stack of packages and removes it from the stack of packages,
in which, following the removal of the at least one package from the stack of packages, the at least one hand element is displaced along the at least one rail, and
in which, following the displacement along the at least one rail element, the at least one hand element grips at least one further package from the stack of packages and removes it from the stack of packages.
